If I bet a game ATS (lets assume college basketball) blind, I'm supposed to lose 4.55% in the long run, right?
This is, if I bet $110, I'm expected to lose $10 for every $220 invested. (50% of the time I lose $110 and 50% I win $100)
BUT
Lets say I bet blind all the games whose closing line at all or almost all SBs is +7.
According to the half-point calculator, there's a 4.03% of a PUSH, therefore I'm not losing and winning anymore 50% of the time, right?
Lets round to 4%, so, I push 4%, win 48% and lose 48%
Therefore
EV%=((100*.48) - (110*.48))/110 = -4.36% instead of -4.55%
Same for every other number
Am I doing this wrong?
